0mm AND BUTTER-WORKER.

Specification of Letters Patent.

Patented Oct. 2 7, 1914.

Application filed. .Tune 9, 1913. Serial No. 772,582.

To all whom it may concern:

Be it known that I, LEVI A. DIsBRow, a

citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Churns and Butter-VVorkers, of which the following is a specification. I s j My invention relates to combined churns and butter workers and has for its object to provide such a structure which shall-be simple and eflicient in operation, have relatively few parts and'have' these parts so arranged as to be particularly accessible for cleaning purposes. I

It is also an object of my invention to provide a movable shelf and slicer'bars in combination witha central roller having an angular relation such that all ofthe butter in the churn will at each revolution of the same be carried beneath said roller and upon and over or between said slicer bars.

In my prior PatentNo. 958,738 I proposed to-u'se a central'roller in combination with a shelf and a series of slicer bars. Each of these slicer bars and the shelf were, however, radially positioned with respect to the roller, the result being that a considerable part of the butter'might be carried by the shelf entirely above and over the roller, which proved unsatisfactory in operation and required the use of a multiplicity of slicer bars, three being shown in the said patent although even that number was insufficient for the best work with radially positioned bars and shelf. As the result of extended tests and experiments I have discovered that by placing the shelf so that the surface thereof extends obliquely with respect to the radial line passing through the axis of the roller or in the plane of a chord extended across the drum at a point materially removed from the roller and positioning the slicer bars with the operative portions thereof between this lane and the roller, not only will all of the utter invariably be, passed over or between said slicer bars and be much more eificiently'worked than if radial elements were employed, but no more than two of such slicer bars will be I required. Such an organization is shown roller, the front edges of the slicer bars in'this application. The slicer bars also are turned relative to the roller so that the plane of any surfaceof said slicer bars is not radial with respect to the axis of the being beveled and having the planes of such beveled portions extending obliquely forward of a plane passing through the axis of the roller and the most forward portion of said slicer bars.

The full objects and advantages of my invention will appear'in connection with the 'detaileddescription thereof and are particularly pointed out in theclaims.

.In the drawings, illustrating the application of my invention in one form, Figure 1 is a side elevation of a churnemploying features of my invention. Fig. 2 isa sectional plan view with some parts broken away. Fig. 3 is a sectional elevation view. My improved churn-comprises an outer cylindrical shell or'drum 10 and end membersgll and 12, saidend members being supported by trunnions 13 in bearings 14 formed at the top of standards 15;. The churn is driven by means of gearing 16 from a pulley 17 in a well-known way.

The trunnions l3c'are hollow and through the hollow portions thereof shaft 18 of a central roller19 which may be of any desired form and is shown as having extends the a four wings 20. The gearing illustrated drives the drum 10 in one direction'and the in a chord of the circumference of the drum, which plane will cut the radius of the drum from the axis of the roller at approximately its middle point, the shelf being of such width as to leave a'space be tween its inner edge and the drum approximately equal -to the width of the shelf.

The lower side of "the shelfis preferably beveled at each edge, there being a space 22 between the shelf and the drum wall which is essential for producing satisfactory results, as this permits water to drain back as the shelf comes up.

Disposed so as to have'the operative p0rtions thereof extend above theplane of the shelf '21 is a slicer bar 23 having a beveled edge surface 24 adjacent the shelf 21. Said slicer bar is turned obliquely with respect to a plane passingthrough the axis'of the roller, allsurfaces of such slicer bar being oblique to such a plane, asclearly shown in Fig. 3. The slicer bar 23. will be so positionedthat the roll of butter from the shelf- 21 will, by gravity, tend to descend against the beveled face of this slicer bar and Will come within the action of thewings20on the roller 18, which will draw said roll of butter inwardly and squeeze the same-upon and over the beveled face'2et' and exposed upper edge of the slicer bar 23. It 1s practicable, and in many cases desirable, to employ another slicer bar 25,-wh1ch wilt roller 19 exactly as is slicer-bar 23, that is, all surfaces ofslicer bar 25 will be in planes oblique to a plane passingthrough the axis of roller 19. K

In view of the fact that slicer bar 25 is relatively at the rear of slicer bar 23, it-

will have to occupy a position cross sectionally oblique to that of slicer bar 23in order that the faces thereof may have the'same relative position with respect to roller 19. It will be seen that butter which is turned over the edge of slicer bar 23 will be forced upon the surface 26 of slicer bar 25 and squeezed between the slicer bars and over the edge of slicer bar- 25 bythe wings 20' of roller 19 before descending. to the bottom ofthe drum. In'no-case, wherethe slicer bars and shelf are relatively positioned, as herein shown; is there any need for more than two slicer barsto most effectively Work the butter after the same is churned.

At suitable distances fromshelf 21, I provide a series ofshort projections-27, preferably backwardly beveledin respect to the direction of rotation of the drum. These bars 27 keep the butter rolling at the bot tom so that the buttermilk-and water may come next to the interior of the drum and sliding or smearing of the butter will be prevented.

It isto be noted thatthe arrangement of shelf and slicer bars in respect to the drum 19 as shown in this application not only gives an organization of parts in the highest degree efl'ective in the working of the butter,-but is also equallyeflicient in aiding the churning, as the cream is caused-to pour from the shelf 21 upon the slicer bar 23 and from there is deflected againstthe roller '19, fromwhich it is thrown back upon the slicer bar 25 giving exactly the right stirring and breaking action.

The advantages of my invention are obvious and have'been fully pointed out in the detailed description thereof.

I Itwill be apparent that a combined churn and-butter worker madein accordance with the principles of my invention may be man- 'ufactured cheaply and will be extremely convenient to -useand keep clean.

I claim:
